MOTOROLA SEMICONDUCTOR TECHNICAL DATA 1.1GHz Dual Modulus Prescaler The MC12026 is a high frequency, low voltage dual modulus prescaler used in phase-locked loop (PLL) applications. The MC12026A can be used with CMOS synthesizers requiring positive edges to trigger internal counters such as Motorola's MC145xxx series in a PLL to provide tuning signals up to 1.1GHz in programmable frequency steps. The MC12026B can be used with CMOS synthesizers requiring negative edges to trigger internal counters. A Divide Ratio Control (SW) permits selection of an 8/9 or 16/17 divide ratio as desired. The Modulus Control (MC) selects the proper divide number after SW has been biased to select the desired divide ratio.
